Abstract (en)
[origin: EP0532751A1] This invention relates to a transverse discharge pumping type pulse laser oscillating device including an electron capturing gas, especially to the configuration of preliminary ionization electrodes (4a, 4b, 8a, 8b). A transverse discharge exciting type pulse laser oscillating device according to this invention has preliminary ionization parts such that the dominant parts of corona discharge are directed to the part between main electrodes (1, 2) and the developing lengths (1) of the corona discharge are long. The long developing lengths (1) increase the quantity of emitted ultraviolet rays and the electrodes (4a, 4b, 8a, 8b) are so arranged that the air between the main electrodes (1, 2) is irradiated with ultraviolet rays emitted from near the initiating regions of the corona discharge the initiating regions emitting light whose intensity is greater than those of other regions in the corona discharges. Thereby a homogeneous main discharge is obtained and the efficiency of the laser oscillation is improved. <IMAGE>
